The calibrations during the afternoon went well.
We started observing around 9:15 pm and the first image was a zero. Then we took an r-band image (225772) of the bright star for centering and we realized that the stars had a donut shape. We thought it was a focus problem and then we pressumed that something was going wring with the hexapod.

Tim tried to diagnose the problem, talked with people in US and solved the problem around 2 am. We started doing science observations at 2:25 am and the system worked until 3:16 am. The last image we took was an i-band image of 30 seconds exposure (257808). Once the image was taken, we heard a beep from the system and we saw that the queue has halted. We saw that the hexapod X,Y and Z numbers in the GUI window went to very high values and the Status of Hexapod changed to Error. The Error message is {"fatal".'5"',"warning","5"}, and it's the same that appeared at the begginign of the night. We decided to stop doing any observation.
